“lifted up my hand.” One way a person swore a solemn oath was to raise his hand and swear. We still raise a hand and swear in our courts of law today, so this custom, thousands of years old, still survives in various forms. We see the custom of lifting up your hand to swear an oath in many places in Scripture (Gen. 14:22; Deut. 32:40; Ezek. 20:5, 6, 15, 23, 28, 42; 36:7; 44:12; 47:14; Rev. 10:5). Another ancient way of swearing was to hold the genitals of the one to whom you were swearing (see commentary on Gen. 24:2).
